Do Air Purifiers Help with Smell?


Air purifiers can be your allies when banishing unwanted smells from your living space. Air purifiers work to offer you a fresher indoor environment. These devices are designed to capture and eliminate particles that contribute to bad odors.

Air purifiers employ filters to trap airborne particles that carry odors, including pet dander, smoke particles, and other scent-causing agents. As they filter the air, these purifiers help reduce the concentration of these particles, leading to a noticeable improvement in indoor air quality.

However, not all smells can be removed. The United States Environmental Protection Agency (EPA) states that it’s possible to make the air inside cleaner and fresher by reducing indoor air contaminants. It may not, however, eliminate all odors and lingering scents. Still, it won’t work for all odors and lingering smells.

Plus, the placement of air purifiers plays a big role in their functions.

Do Air Purifiers Help with Pet Odor?


Pet odors often arise from microscopic particles, like dander and pet hair, that become suspended in the air. Air purifiers are equipped with filters that can capture and trap these particles. For example, high-efficiency particulate air (HEPA) filters are extremely effective at capturing small particles, producing cleaner and fresher air.

Moreover, some advanced air purifiers have specialized filters designed to tackle pet odors. As a result, not only are the larger particles removed, but the very compounds responsible for the lingering odors are also broken down.

Even though air purifiers can significantly reduce pet odors, it’s important to remember that your dogs must be groomed and cleaned regularly, and your home needs enough ventilation.

Do Air Purifiers Help with Smoke Smell?

Do Air Purifiers Help with Smoke Smell?

Smoke smells from cooking, tobacco, or other sources can linger and permeate your living space. Especially, second-hand smoke is especially bad for kids, pregnant women, and the elderly. Fortunately, air purifiers can help with smoke smells.

How Smoke Odor Spreads

Tiny particles, called volatile organic compounds (VOCs), are released when something burns. These VOCs mix with the air and find their way into every nook and cranny, resulting in that persistent smoke smell.

How Air Purifiers Combat Smoke Smell

Air purifiers designed to handle smoke odor employ various methods to combat it. HEPA filters are a common component. They can capture tiny particles, including those carrying the smoke smell. Some purifiers also feature activated carbon filters. These absorb and trap VOCs, effectively reducing the odor in the air.

What Causes Bad Smells in My Home?

What Causes Bad Smells in My Home?

Unpleasant odors can stem from various sources. Here are some common culprits:

  • Poor Ventilation: Inadequate airflow can lead to a buildup of stagnant air and unpleasant odors.
  • Dirty Carpets and Upholstery: Carpets and upholstery can trap dust, dirt, and spills, leading to odors over time.
  • Cooking Odors: Cooking strong-smelling foods can release lingering odors in your home.
  • Pet Odors: If you have pets, their fur, dander, and accidents can contribute to bad smells.
  • Mold and Mildew: Moisture-prone areas like bathrooms, basements, and kitchens can develop mold and mildew, producing musty odors.
  • Trash and Recycling: Accumulated trash and recycling can emit foul odors.
  • Stagnant Water: Standing water in drains, sinks, or unused appliances can produce unpleasant odors.
  • Household Chemicals: Strong cleaning agents or chemicals can leave behind harsh odors.

How Do Air Purifiers Remove Smell?

How Do Air Purifiers Remove Smell?

In this part, let’s delve into the science of how these devices work to remove unwanted smells from the air.

Filtration Methods

Air purifiers use various filtration methods to target and eliminate odor-causing particles. One of the primary technologies is the HEPA filter. This fine mesh traps tiny particles, including odor molecules, as air passes through it. Additionally, activated carbon filters play a vital role. These filters contain a porous material that absorbs and holds onto odor molecules, effectively neutralizing them.

Ionic Purification

Some air purifiers employ ionization technology. These purifiers release negatively charged ions into the air. These ions attach to odor particles, causing them to become heavy and fall onto surfaces in your home.

Ozone Generators

While less common due to potential health concerns, ozone generators are another method. These machines release ozone, which can react with odor molecules, altering their chemical structure and neutralizing the smell.

UV-C Light

Certain air purifiers utilize ultraviolet (UV-C) light technology. UV-C light breaks down odor molecules and kills bacteria, viruses, and mold that might contribute to unpleasant smells. This technology is particularly effective at targeting biological sources of odors.

Combined Approaches

In many cases, air purifiers combine multiple technologies for enhanced effectiveness. For instance, a purifier might incorporate HEPA filtration, activated carbon, and UV-C light to comprehensively address various odor sources.
